CLEANING STEAM-BOILERS.

SPECIFICATION.forming part of Letters Patent No. 253,453, datedFebruary-7, 1882.

Application filed August 2-1, 1881 (No model.)

To all whom "it may concern:

Be it known that I, JOSEPH B. WEEKs,a citizen of the UnitedStates,residentof Barnesville, in the county of Belmont and Slate of 5Ohio, have invented a new and valuable Improvement in CleaningSteam-Boilers; and I do hereby declare that the following is-a full,clear, and exactdescription of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is arepresentation ofa side view, partly insection; and Fig. 2 is I a cross-section of one of the pipes.

This invention has relation tosteam-boilers; and it consists in thenovel construction and arrangement of parts, as will be hereinafterfully described, and pointed out in theclaim.

Referring by letter to the accompanying drawings, A designates theboiler.

B designates a Wrought or cast iron pipe, perforated in three rows, theperforations being about twelve inches apart and so arranged as not tobe opposite to each other. These perforations vary in size.

0 designates a pipe for permitting the dis tribution of the pressure,and thereby causing the boiler to be cleaned throughout its entire 0length. This pipe (3 does not extend the entire length of theboiler,butis connected at its front end to the pipe B by an L-joint and at itsrear end bya T-joint, which latterconnects with the outlet-pipeD. Theoutlet proper, D,

5 is about one-halt inch larger in diameter than the pipes B and U,forthe purpose of effecting a ready escape for the sediment, antLisattached to the boiler by lock-nuts, with copper or lead washers; and ispassed through the boiler either above or below the water-line. The pipe0 is located about six inches above ,the pipe B. The pipe B may besuspendedin the boiler, or may rest on the bottom of the same. The pipeGhas a coupling or union 5 joint, E.

By turning the valve, before starting on with a small weight of steam,it will thoroughly clean the boiler of mud, and by thus keeping theboiler clean will prevent foaming.

A graduated double canal,increasin gin size from the rear to the frontof the boiler, the lower portions of the sections of which it is formedbeing perforated, and the upper portions of the sections being connectedby vertical pipes to cisterns having closing slides, has been locatednear the bottom of theboiler and connected to a tap at the lower frontend of the boiler. A mud receiver or collecterapplied to the outside ofthe shell of the boiler and to the bottom side thereof, with a series ofperforations made in the shell of the boiler to communicate with saidreceiver, has been connected with a perforated tube arranged at aboutthe water-surfaceof the boiler and leading outside of the same. Aconduit gradually increasing in size and leading out of the boiler isalso old and neither of these constructions is claimed broadly.Protection is asked only for the construction hereinafter specificallyclaimed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a device for cleaning steam-boilers, the combination, with the boilerA, of the perforated pipe B, having perforations of unequal sizearranged so that no two are opposed, and the pipe 0, having theunion-joint E, and being connected to the pipes B and D by L andTjoints, and the pipe 1), having the valved 8o outlet D, substantiallyas and for the purposes specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JOSEPH B. WEEKS.
